摘要： [PROBLEMS] To provide a ball end mill capable of increasing a feed speed and a depth of cut by suppressing vibration to increase a cutting efficiency. [MEANS FOR SOLVING THE PROBLEMS] This ball end mill (1) comprises ball edges (6a to 6c) having first edge parts (6a1 to 6c1), second edge parts (6a2 to 6c2), and third edge parts (6a3 to 6c3). Since a first radius of curvature (R1), a second radius of curvature (R2), and a third radius of curvature (R3) are set to be different from each other, the vibration of the ball end mill (1) can be suppressed by changing the direction of a cutting resistance (cutting torque) given from a work (20) to the ball end mill (1) in the radial direction of the ball end mill by the first edge parts (6a1 to 6c1), the second edge parts (6a2 to 6c2), and the third edge parts (6a3 to 6c3). As a result, the feed speed and the depth of cut can be increased to increase the cutting efficiency.

摘要： A screw member capable of being reduced in size and weight. A pair of side wall surfaces (18) of each of six torque transmitting parts (16) lie on lines passing through the center line(O) in a sectional shape perpendicular to the center line (O) so as to transmit torque via the side wall surfaces (18), whereby the direction of a surface orthogonal force N applied from a screw tightening tool agrees with the direction of a tightening−effectuating tightening force F at a point of force application Q to which a tightening torque is transmitted. The above arrangement reduces a turning operation force applied to the screw tightening tool and a load acting on a torque transmitting part (16) in comparison with a conventional hexagonal head (100), and decreases the diameter of the head (12) of the screw member (10) to reduce the size and weight thereof while avoiding the crash or the like of a torque−transmitting side wall surface (18).

摘要： Provided are: a hard lubricating coating film which is hard and has wear resistance; and a hard lubricating coating film-covered tool. A hard coating film (10), which is hard and has wear resistance, and an end mill (12) can be obtained by alternately forming two or more (CraMobWcVdBe)1-x-yCxNy layers A (22) and two or more (CraMobWcVdBe)1-x-y-zCxNyOz layers B (24) by controlling the composition ratios of Cr, Mo, W, V and B and various reaction gases during the film formation, or alternatively by controlling only the various reaction gases during the film formation. In this connection, the atomic ratios a-e, y and (x + y) of the layers A (22) are within predetermined ranges; the atomic ratios a-e, x, y, z and (x + y + z) of the layers B (24) are within predetermined ranges; the film thickness (D1) of the layers A (22) is within the range from 2 nm to 1,000 nm (inclusive); the film thickness (D2) of the layers B (24) is within the range from 2 nm to 500 nm (inclusive); and the total film thickness (D) is within the range from 0.1 µm to 10.0 µm (inclusive).

摘要： Provided is a drill that achieves a shape of chips curled without a needle-like projection and accordingly shortened in overall length and that more smoothly discharges the chips to further improve a tool life. Since a cross section orthogonal to an axial center C of a drill 10 has a first convex curve CL1 corresponding to a convexly-curved cutting edge portion 12a and a first concave curve CL2 corresponding to a concavely-curved cutting edge portion 12b intersecting with each other at an intersection A, chips generated from a cutting edge 12 are curled and formed into a shape having no needle-like projection and accordingly relatively shortened in overall length and are smoothly discharged with enhanced discharge property and, therefore, the tool life of the drill 10 is further improved.

摘要： A radius end mill enabling an increase in durability by reducing cutting resistance, a reduction in the wall thickness of chips and a reduction in weight, and preventing it from being damaged or poorly worked due to the interference of the chips by discharging the chips smoothly. The radius end mill comprises a spiral-shaped outer peripheral blade (2) generally formed in a roughly cylindrical shape and formed on its outer peripheral part (1), a bottom blade (4) formed at its end face part (3), and an R blade (5) formed at a corner part where the outer peripheral blade (2) intersect the bottom blade (4). The ridge line (6) of the bottom blade (4) is formed of a projected arc-shaped circle of curvature in plan view starting at the center O of the end face part (3) to the free end X of the R blade (5) intersecting the ridge line (7).

摘要： In a cold forming tap of the embodiment, those projections, which constitute a part of the projections and are axially adjacent to one another, are removed to valley bottoms, and cutting blades, a diametrical dimension of which corresponds to a thread inside diameter of a female thread that should have been formed at portions corresponding to the valley bottoms of the removed projections, are formed. In manufacturing the cold forming tap, a maximum diameter of a valley bottom is not formed in relief portions contiguous to projections of male thread portions but concave and convex configurations of peaks and valleys are in synchronism with one another in a circumferential direction, so that peaks and valleys of the male threads can be efficiently formed at one time with high precision in a processing called a thread grinding, in which grinding is carried out by a grinding stone formed at its outer peripheral surface with threads, and a dimensional management of the male threads is made much easy to enable easy and inexpensive manufacture of high-precision cold forming taps.
